Accessibility

HerbDev is built to work for more people.

HerbDev strives to make HerbDev.com usable by as many people as possible, including people who navigate by keyboard, enlarge content, or use assistive technology. WCAG 2.2 Level AA is the site’s engineering and testing target.

Current accessibility status

HerbDev.com has been audited and hardened against the automated WCAG 2.2 Level A and AA rules available in axe-core. The completed review covers 48 top-level HerbDev pages at desktop and mobile widths, with no automated accessibility violations reported. Interactive vocabulary and guided-course lesson views were checked separately. Standalone project demos and examples are outside this main-site review.

Automated testing cannot prove complete WCAG conformance. Meaningful alternative text, screen-reader usability, reading order, cognitive clarity, transcript accuracy, touch comfort, and real-world task completion also require human judgment and continuing review.

What has been implemented

A keyboard-visible skip link and consistent page landmarks.
Visible keyboard focus treatments and keyboard-operable navigation.
Improved text contrast and non-color identification for inline links.
Accessible names for frames, carousels, and scrollable regions.
Larger carousel controls that meet the WCAG 2.2 target-size minimum.
Programmatic form labels, autocomplete guidance, and announced contact-form errors.
Reduced-motion support on shared and affected animated surfaces.
Native audio controls and on-page transcripts for narrated articles and vocabulary definitions.
Vocabulary definitions available on hover or keyboard focus, with a dismissible popup and direct entry links.
Keyboard-operable recall questions, course checkpoints, saved terms, and recent history, with feedback announced in status regions.
Cookie-notice handling that keeps focused controls visible and preserves focus after dismissal.
Automated regression checks across the top-level HerbDev pages.

Ongoing review

Accessibility is an ongoing process. HerbDev continues to review keyboard behavior, zoom and reflow, focus visibility, image alternatives, link purpose, form recovery, transcripts, touch operation, and compatibility with assistive technologies.

Recent browser checks covered skip links, desktop and mobile navigation, popup dismissal and focus, audio playback, recall feedback, saved-state persistence, blocked browser storage, and representative layouts at 320 and 640 CSS pixels. These checks do not replace testing with people who use screen readers and other assistive technology.

New content and interactions are expected to follow the same accessibility target and automated regression checks before publication.
